In this thesis，we design a CPW-fed dual-band
monopole，which have the bandwidth covers IEEE 802.11
a/b/g。This monopole antenna have good polarization
isolation and stable antenna gain. And then, we design
a loop antenna for Wireless In-building Network
application which can be used as the antenna of control
Module. This antenna enhances the bandwidth of loop
antenna to cover the IEEE 802.11 a. The loop antenna
have unidirectional radiation pattern and stable
antenna gain.
